WINDING liIACI-IINE.

Our invention relates to improvements in means for controlling the operation of winding machines or other apparatus and particularly to auion'iatic s;opping-inechanism tor arresting); the operation of the machine in cases ()ftllltl'gclltj ()ur improvements are herein shown as; applied to a machine tor winding clcctricahcoils in which the winding-spindle or mandrel is continuously rotatcd. and the wire-guide, which deposits the turns of the windin in place on the mandrel, is given an intermittent feed or traverse with a reversal in the direction of feed at opposite ends ot the coil.

Such a type of winding machine de scribed and illnstrated in onr U. 2 Letters Patent No. lAZiSJQl, dated June 112, i923, and No. 'lyltjSfiS-Jlated Aug. T, i923, from the former oi which the present case divided; but it in to be understood that the present improvements are applicable to various types of apparatus einplo red tor other purposes, and the im'ention is not tlrei'clore limited in thi: respect to the particular embodiment herein shown and described.

The principal object o'l our improvement is, in general, to provide a stopping-inexhanism tor arresting the operation ot the apparatus in case ot abnormal conditions tending to rt. st the proper functioning oi the mechanism; and in particular. as applied to a winding machine to stop the nnu'hine whenever the wire-guide encounters undue tance to its food eo that the operating parts of the tcetiing-inechanism shalt not be strained, broken or disruptei'l in their orgiinization. i k The manner and means i r carrying out the improvement are fully describcil in the following specification, illustrated by the accompanying drawings, in which like re tcrcnce characters designate like parts. In the drawings:

Fig. 10, a side elevation of the same in det Referring first to Fig. l, the Winding machine herein illustrated comprises, in general, a horizontal frame or "bed B mounted on suitable legs or standards, one of which B partly shown atthe left and more completel illustrated in end elevation in Fig. 3. thiruu'ninting the bed B at its left-hand end is a lixed headstock C provided with bearings e, e for the rotating winding-spindle S. at the ri;,;'ht-hand end of the bed B is an adjustable tailstocl; D carrying a sleeve l slidable in a split-bearing t/ which may he clamped thercaround by a handscrew .l-l exlemling through the split; portion ol the bearing. .lonrnaled in the sleeve F is a lire-spindle 1% formed with a pointed end adapted to support the outer extremity ot' the winding-mandrel A, the opposite end o't which is secured to the winding-spindle S means of a suitable chuck G. The above described arrangement is similar ,to that employed on lathes and other machine-tools and provides for removal and replacement oi the mandrel or arbor A, as occasion requires, by sliding the sleeve F outwardly in its bearing (7. The niandrel A carries a detachable former or core K on which the wire is wound to produce the coil, and at its ends are removable heads or flanges 7c, in which serve to hold the windings in place.

' Arranged opposite the winding-mandrel til herein. Suflice it tostate that while the present improvements have been shown as applied to a traverse-mechanism of this type they are also adapted for apparatus of a different arrangement or method of operation and might be used on other styles of machines employed for entirely different work.

Referring to Figs. 1, 2 and 3, the driving-connections for the machine are arranged at its left-hand end and enclosed within the walls of the headstock C and the sides of the leg or standard B. As shown more particularly in Fig. 3, a bracket 33, bolted to the inner side of the front walls of the leg B at 3%, 34 is formed with arms 35, 35 terminating in spaced-apart hubs 3(3, 36, see also Fig. 1. The hubs 36 are bored to receive bushings 37 which project beyond their outer ends to adapt them to enter the bores of two spaced-apart hubs 38, 38 serving as a pivotal support for a swinging bracket T0. The bracket 40 is formed with two arms 41, 41 depending from the hubs 38, 3S and joined together by a lower, elongated hub 42. J ournaled in the hub a2 is a shaft 4-3 which carries a flanged belt-pulley A fast on one end. The opposite end of the shaft 43 is reduced in diameter at 45 where it enters the bore of a pinion at? which is held in place thereon by a nut 48. The pinion 4'? meshes with a gear 49 which is held fast on the shouldered end of a shaft 50 by means of a nut 51. The shaft 50 extends through the bore of the bushings 37 in the spaced hubs 36 of the fixed bracket 33, and is free to rotate therein when driven from the shaft 43 through the gears 47, 49. Secured fast on the shaft 50 centrally thereof is a sprocketwheel 52 arranged between the hubs 36, 36 of the bracket 33 whereby to hold the shaft in place in its bearings. The sprocket-wheel 52 is connected by a drive-chain 53 with a sprocket 5d" keyed to the winding-spindle S and enclosed within the headstock C, as shown in Fig. 1. Through these connections the spindle S is driven from the belt-pulley t-l through the gearing 17, 49 at a reduced rate of speed. The pulley 4H is conneetia'l with the source of power, which may be a motor, line-shaft or any other prime-n'iover, by means of a belt 55 which passes through the rearward side of the standard B as shown in Fig. 3. Normally, when the machine is .at rest, the belt 55 runs slack over the pulley -14, as here illustrated, and the pulley is held from turning by a friction-brake 56 which bears against its periphery on its rearward side. The brake 56 comprises a main brake-shoe 57 mounted on a rod 58 which extends between two brackets 59, 59 fastened to the rear wall of the standard B by bolts (30, see Fig. 9. The brake-shoe 57 carries a curved, spring-metal plate 61 which is faced with a lining 62 constructed of leather or other friction-producing material which forms the contact-element for the pulley er. As shown particularly in Fig. 10, the plate or auxiliary brake-shoe 61 is bent on a radius slightly less than that of the rim of the pulley *l-l so that as the latter moves into contact with it the outer extremities of the shoe 61 will engage the pulley first. As the pulley 4% is carried firmly against the shoe (51, however, the ends of the latter will expand so that tinally its entire brakingsurface makes frictional contact with the periphery of the pulley as illustrated in Fig. 3. The purpose of this arrangement is to provide for regulating the braking action so that the rotation of the pulley H will be stopped with a grzulual retardation and started with a corresponding acceleration in its speed. In other words, the yielding spring brake-shoe (51 acts as a cushioning device or shock-absorber for overcoming momentum and inertia and preventing sudden strains being imposed on the moving parts.

The pulley 44 is moved into and out from contact with its brake 56 by the swinging action of its supporting bracket -l-O under the control of a tension-spring 63. As shown in Fig. 3 the spring (33 is anchored at (i lto the rear wall of the standard 13 with its opposite end connected to an elbow-shaped arm (35 on the bracket 40. The arm (35 forms a continuation of one of the arms ll of the bracket 40 and reaches downwardly with a flat plate 66 at its end. The plate (36 makes contact with the end. of a stud (3T screwed through the upper end of an upright lever 68, the head of the stud 67 being adapted to engage the rear wall of the standard B to limit the throw of the lever. The lever 68 is mounted fast on a rod or shaft 69 journaled in bearings 70 on the opposite. sides of the base of the standard B. l lxtending forwardly from the rod 09 is a. lever 72. mounted fast thereon and formed at its outer end with a treadle 73 arranged in convenient position to receive the operators foot as he stands at the front of the machine.

Pivotally (Ol'lllttl'ttl to the outer end of the treadle-lever 72 at Tl is a flat rod or bar $5 which reaches up thrm gh the machine-bed l3 and projects above the top of the base of the headstock C. The rod 75 s guided at its upper end in a PliliO-llh't bearing '76 sccured to the headstock (l at 7T, 77, see Figs. 4- and 8. The rod 75 serves as a control element for holding the treadle-lcver 72 depressed during the operation of the machine, and for this purpose it is adapted to be engaged by suitable detent-mcans as next de scribed. Journaled in a learing 78 on the base of the li aidstock C is a rock-shaft 79, see Fig. 8, carrying a detcnt-hiver 80 secured fast on its inner end by a set-screw S1.

The inner ends of the pins 115 are beveled on opposite sides to form Vshaped points 116 which seat in correspondin cl shaped recesses 117 on the pe' riphcrv ot the hub 105. Preferably the re- .Hltfi 11.7 are formed in the ends of hardened 118 set in radial bores in the hub 105 wnh their outer extren'iities flush with the periphery thereof. The plnng'enpins 11.1 are held. in engagement with the rec in the phtigs. 118 by means ot a wire springthe ring 1.12 and passingthrough slots 1 1 in the ends of the pins. The spring-ring 120 is seated; in a spi al' groove 122 on the ring 112 with one of its ends 123 bent radially inward and held in it here 124: as illustrated in Fig. 5. As shown in (3, the body of the rear 7 is provided with a plurality of transverse bores 125 to which are titted transvery-2e pins 126 which. are free to slide therein. The inner ends (it the 1 ins 1.26 project through the side of the ear '1" and are "formed. with opposite. heveled races 12? similar to the hevels on the radial pins 115, but of slightly less incl nation. Formed in the vertical taco ot the huh 105 are hevclciil recesses 128 with which the hevelcd ends 12? ot the pins 126 engage. Attheir outer ends the pins 126 are reduced in diameter at Q9 and riveted through a plate or disk-washer 1?) l. The wisher or disk 130 is titted to slide on the hub 107 of the gear 7 and normally is received within an undercut recess 131 on the side of the gear. As shown in Fi 1, the outer face of the disk 130 hears against the rounded end of the lower arm 10% otthe lever 1052. Re- 101"].111 to Fig. 7, the gear 7 is formed with a transverse here 132 which provides a pocket for a coiled spring 133. One end. of the spring 133is anchored-to a pin 13% driven into the gear 7 to .Xtcnd across the bore or pocket Ill 132 while its opposite end 135 is riveted through the plate 130, tending to maintain the latter within its recess 131.

It will be seen from the foregoing description that the gear 7 forms the connection between the drive-shaft O and driven shaft 0. both when the gear is active to drive the train of gearing on the countershaft l. or when it is employed sole'ly as a clutch-meniher to couple the shafts together by means of its hub 107 and the opposite clutch-element 110. It is also to be observed that .the gear 7 is'connectcd rotatively with the drive-shaft through the hub 105 inductively. That is to say, the gear 7 may be turned rotatively the hub 105 against the resistance of the plungernns 115 bearing against the beveled recesses 117 in the hub. Should the rotation of the driven shaft 0 be resisted under abnormal stress then the tendency will be for the hub 105 to turn within the gear 7 and this action will cause the pins 115 to ride up the sides of their beveled sockets while 0X panding the spring-ring 120. hleanwhile this relative rotation between the hub 105 and gear 7 will also cause the transverse pins 126 in the gear 7 to be slid to the right, as viewed in Figs. 4. and 6, under the action of the inclined pockets 128 on their beveled ends 127. In this way the disk 130 is slid to the right to rock the lever 102 to slide the bar 88 to the left. where-by to release the detent means and. arrest the operation of the driving-mechanism. The method of operation of the complete apparatus is as follows:

Referring first to Fig. 3, when the treadlee lever 72 is in its raised position, as here shown, the bracket 10 will be swung back to press the driving-pulley -11 against its brake 56, and the belt will run slack over the pulley without turning it. lVhen it is desired to start the machine the operator places his foot on the treadle 73 to depress the lever 72 and this action rocks the arm 68 on the shaft 69 to the right, causing it to act through the arm on the bracket to swing the latter in the same direction against the tension of its spring 63. The pulley ":ttt: will thus be carried away from the brake 56 which releases it gradually while the ends of the brake-shoe 61 contract inwardly as shown in Fig. 10. As the pulley 1 t moves to the right it takes up the slack in the belt 55. which. as it tightens on the periphery of the pulley, starts its rotation with a gradually accelerated speed until the full driving speed is attained. As before. explained, the pulley 44 is fast on the shaft 13 and the rotation of the latter is transmitted through the gears 47 and 19 to the shaft 50. The shaft 50 turns the sprocket 52 and through its chain 53 transmits rotation to the upper sprocket 51 which drives the winding spindle S. As shown in Fig. 1. the spindle S is connected. to rotate the mandrel A to wind. the

wire 10 onto the former or core K as it is fed thereto by the traverse-guide T. Referring now to Fig. 2, it has before been explained that the spindle S drives the shaft 0 through the operation of the cam V acting on the lever 25 to turn the ratchet-wheel 15. Therotation of the shaft 0 is transmitted either directly through the clutch R, or through the train of gears on the countershaft If. as may be selected, to turn the screwshaft- 0. the impulse f the ratchet-drive is intermittent and as the winding-mandrel completes each turn in its rotation the screw 0 acts through the nut or follower P, see Fig. 1, to advance the wire-guide T along the core K to an extent equal to the thickness of the wire being wound. As the guide T moves from one end of the former K to the other it deposits the wire onto the coil in av series of parallel, adjacent turns or convolutions which form a layer extending between the guidingilanges or heads 7c, 70. As each layer of the coil is completed the direction of feed of the guide is reversed through the automatic operation of instrumentalities not herein shown or described, but which are fully explained in our U. S. Letters Patent No. 1.10353 1 before referred to.

Under normal conditions the machine operates continuously to feed the wire 10 into place on the former K while traversingit back and forth to build up the coil in superimposed layers of parallel turns or convolutions. At the start of the winding, or sometimes in finishing the coil, it is desirable to maintain the machine under full control of the operator in order that its operation may be immediately arrested should the apparatus be incorrectly adjusted or fail to function properly. To provide for thisthe detent-devices which render the driving-mecha-.

nism active for continuous operation are not engaged automatically but must be set by hand to hold the starting-treadle 72 depressed. lVhen the machine is at restthe slide-bar 88, see Fig. 1, is held against the action of its spring 98 by the engagement of the toe 94 on the lever 92 with the notch lVith the parts thus engaged the rockshaft 79 will be maintained by the arm 87 on the lever 85 in position to hold the detentlever 80 free from the stop-plate. 88 on the vertical rod 75. see Figs. 4 and 8. lVith the detent-lever 80 thus restrained from action the rod is free to slide up and down under the movement of the treadle-lever 72. Hence. when the foot is first pressed down on the treadle 73 to start the machine if any condition requires instant stopping of the wind ing the operator has only to release the treadle to allow the bracket 40 to swing back to the left, as viewed in Fig. 3, to arrest the rotation of the pulley. 44 which is carried thereby. Through this arrangement the ma- The rotation of the shaft 0 under chine is maintained under manual eontro so that the operator may observe its operation and make sure of the proper tui'ictioning of the winding e len'ients before setting itto ope'zztecontinuously. Now, as the trendlelever is held depressed, it the operator is .intislied that the proper adjustment of the feed of the guide has been inside. to render the ope "ntion of the machine continuoijis it is only nece-ssary'to throw the hand-lever 92, see Fig. 4, to the right. This action li its toe 941: out from the notch 95 in the hair 88 and the latter will therefore he slid to the right under the tension of its spring 98. its the bar 88 moves to the right it acts tl'iroueh the lever 85 to rock the shaft 79 to carry the toe 82 of the detent-lever 80 into engagement with the edge of the stop-plate 83 on the rod 75, as shown. in Fig. 4-. The rod will thus be locked in position to hold the treadle-lever 72 depressed and consequently the driving-n1echz1nisin will he maintained active to continue the operntiijiu ot the innchine without further attention on the part of the operator. When it is desired to stop the machine the lever 92 is rocked to the right again until its handle, coining against the pin 97 in the arm 96 of the lever 85, turns the lever 85 to rock the shaft 79 to release the detent-lever 80. Vi hen the toe 82 of the lever 80 is removed from the edge ot the stop-plate 83 the rod 7 will he allowed to slide upwardly the t-rezidle-lcver T2 rises under the'iinpulse of the bracket e0 es moved by its spring 63, see Fig. 3. As the rod slides upwardly in its bearing 76 the plate 83 rides under the toe 82 of the detent-lever and holds the hitter so that the lever on now be released to allow its too 9% to drop into engagement with the no ch in the slide-her 88. This action locks the lonr 88 againstthe action of its spring ?)8 and with the parts in this relnition the machine is now ready to he SlitlllIOt'l again in the manner as first explained.

The purpose of the action last described is to allow the wire-guide T to be held tor an instant without arretinc' the operation ot the whole machine. That is to say, it the guide meets witha slight resistance to its movement which is quickly overcome, for instance. it the guide-wheel n should strike against a. misplaced turn of the wire in the coil and then ride up over it, the connections between the gear 7 and its hub 105 will vield sutticiently to allow :t'or this slight halt in the teed. It the resistance to the feed not immediately overcome. however, then the continued turning of the hub 105 with respect .to the gear T will act to slide the disk 130 to ettect the disengagement ot the detent-devices as betore explained.

Ilt will be observed that our improvement provides an extremely simple and ellicient; stopping-mechanism which may be maintained under the control of the operator or which may be set to render the operation of the machine continuous as desired. Furthermore, means are provided to stop the machine automatically in case of emergency should the operating parts be hindered in their proper "functioning and in this way the corelated mechanisms are saved from damage or rupture under abnormal stress or strain.

Various modifications might be made in the structure or arrangement of the parts of our improv d mechanism without departing from the spirit or scope of the invention. irloreover, the stopping-apparatus of itself might be applied to other types of machines than thatherein shown. or cmplo rcd for other purposes.
